and forming part thereof a tubular Icontainer embodying my invention'is'illustrated diagrammatically by way of example. In the drawing 1 isa glass tube fully. open at one end, and partly closed at the other by aperforated bottom 6.} A stopper 3 which may consist of parafline or someother material closely fitting the inner wall of the tube is insertedinthe open end of the tube andcanbe pushed farther into the tube inorder to assist in expelling the contents through the hole in the bottom'6. This hole is covered with a small disc 4 of paper, cardboard or someother suitable material, which may be impregnated with some suitablematerial to render it resistive against the contents of the tube and, ifde sired, to make it adhere to the outer wall of the tube surroundingtheho1e2. 5 is a protective layer or coating consisting of a suitablelacquer, such as a collodium solution, this layer or coating beingformed by dipping the bottom end of the tube with the 259,996, and inGermany March 11, 1927.
